strerr(1M) System Administration Commands strerr(1M)NAMEstrerr - STREAMS error logger daemon
SYNOPSISstrerrDESCRIPTIONstrerr receives error log messages from the STREAMS-based log driver
(see log(7D)) and appends them to a log file. The resultant error log
files reside in the directory /var/adm/streams, and are named
error.mm-dd, where mm is the month and dd is the day of the messages
contained in each log file.
The format of an error log message is:
<seq> <time> <ticks> <flags> <mid> <sid> <text>
<seq> error sequence number
<time> time of message in hh:mm:ss
<ticks> time of message in machine ticks since boot priority
level
<flags> T : the message was also sent to a tracing process F :
indicates a fatal error N : send mail to the system
administrator (hardcoded as root)
<mid> module ID number of source
<sid> sub-ID number of source
<text> formatted text of the error message
Messages that appear in the error log are intended to report excep‐
tional conditions that require the attention of the system administra‐
tor. Those messages which indicate the total failure of a STREAMS-
based driver or module should have the F flag set. Those messages
requiring the immediate attention of the administrator will have the N
flag set, which causes the error logger to send the message to the sys‐
tem administrator using mail. The priority level usually has no meaning
in the error log but will have meaning if the message is also sent to a
tracer process.
Once initiated, strerr continues to execute until terminated by the
user. It is commonly executed asynchronously.

NOTES
There is no restriction to the number of strerr processes opening the
STREAMS-based log driver at a time.
If a module or driver is generating a large number of error messages,
running the error logger will cause a degradation in STREAMS perfor‐
mance. If a large burst of messages are generated in a short time, the
log driver may not be able to deliver some of the messages. This situa‐
tion is indicated by gaps in the sequence numbering of the messages in
the log files.
